indifferentketchup 782c2b183d feat: persistent context-window tracker in ChatPane ...

Adds a floating popover above the chat input showing current
context-window usage. Modeled on Paseo's tracker.

- New hook useChatContextStats(chatId, messages) finds the latest
  assistant message in the chat with both ctx_used and ctx_max set,
  computes percent, and returns null when data unavailable.
- New component ChatContextPopover renders a small card with the
  "Context window" label, big percent, and "used / max tokens"
  subline. Hidden when stats is null.
- Color thresholds: <60% muted, 60-85 amber, >85 destructive.
- Not a portal — absolutely positioned inside a new relative
  wrapper around ChatInput in ChatPane.tsx, so it's pane-local
  (multi-pane safe).
- Live updates via the existing messages-array dependency.
- No API / schema / WS changes.
